20100136213 | Thermal Treatment of a Drug Eluting Implantable Medical Device - A coating and a method of coating an implantable medical device, such as a stent, is disclosed. The method includes subjecting the coating to a thermal condition such as a temperature above the glass transition temperature of a polymer included in the coating. | 06-03-2010 |
20110086162 | Concentration Gradient Profiles For Control of Agent Release Rates From Polymer Matrices - The present invention generally encompasses methods of coating which control of the release rate of agents from a polymeric matrix. This control over the release rate of agents provides for control over, inter alia, the therapeutic, prophylactic, diagnostic, and ameliorative effects that are realized by a patient in need of such treatment. In addition, the control of the release rate of agents also has an effect upon the mechanical integrity of the polymeric matrix, as well as a relationship to a subject's absorption rate of the absorbable polymers. | 04-14-2011 |
20110215505 | Medical Device Fabrication Process Including Strain Induced Crystallization With Enhanced Crystallization - Methods of fabricating a polymeric implantable device, such as a stent, with improved fracture toughness through annealing a polymer construct below the glass transition temperature of the polymer of the construct prior to a deformation step are disclosed herein. The deformation of the construct induces crystallization in the polymer construct through strain-induced crystallization. The annealing of the polymer construct accelerates the crystallization induced during the deformation and results in an increase in crystallite density with smaller crystallites as compared to deformation of a tube that has not been annealed. A stent scaffolding is then made from the deformed tube. | 09-08-2011 |
20110260352 | Stabilizing Semi-Crystalline Polymers To Improve Storage Performance Of Medical Devices - Methods are disclosed for improving the storage performance of polymeric stents that reduce or eliminate the effects of long term aging on the properties of the stents. A polymeric stent or a polymeric tube from which a stent is made is heated to a temperature between ambient and the glass transition temperature of the polymer for a period of time. The heating causes densification or an increase in density of the polymer which stabilizes the properties of the polymer in later processing steps and storage. The stent can be made from a polymeric tube that is expanded at a temperature above the glass transition temperature and cooled to maintain an expanded diameter. | 10-27-2011 |
20110260358 | Post Electron Beam Conditioning of Polymeric Medical Devices - Methods are disclosed for conditioning a polymeric stent after sterilization, and/or after crimping and before packaging, such that the properties of the polymeric stent fall within a narrower range of values. The stent is exposed to a controlled temperature at or above ambient for a period of time after radiation sterilization and/or after crimping and before sterilization. As a result, the polymeric stent properties, particularly radial strength and number-average molecular weight of the polymer of the polymeric stent, fall within a narrower range. | 10-27-2011 |
20120045362 | Post Electron Beam Stabilization Of Polymeric Medical Devices - Methods are disclosed for chemically stabilizing a polymer stent after sterilization. The stent is exposed to a temperature above ambient for a period of time after radiation sterilization. The exposure reduces the concentration of free radicals generated by the radiation. | 02-23-2012 |
20120285123 | Methods of Stabilizing Molecular Weight of Polymer Stents After Sterilization - Methods of stabilizing the molecular weight of polymer stents scaffolds after E-beam sterilization are disclosed.
